Patented Mar. 14, 1916l UNITED. ,STATES COMBINED WHEELDIVE leuipnivinorianisivff o? To all 'whom'z'tmay concern: A l 4 Beit known that I, RUssELL L, DAILEY,a

citizen of the United States, residingat Kansas City, inthe countyof Jacksonland VState .of-Missouri, have' invented certainnew and useful Improvements in lCombined Wheel Driveand Guide Mechanism forMof tor-Cars, of which the following is a rspecification. l v This invention relates to. combined wheel drive and `guidemechanism formotor car trucks and the like, where it is desirable to drivel all four wheels,f:md my object is to lproduce a mechanism of this: character which operates efficiently, bywvhich lubricant is retained and from which dust and v dirt are excluded. f

With .this general objectin view ,the invention consists in certainl novel, and :peculiar features of constructionand combinations of parts as hereinafter describedand claimed; `and invorder that it may bev fully understood reference is to be had to the accompanying drawings, in which: f

Figure 1,.is ahorizontal section on lthe line I-I of Fig. 2, Fig..2, is a central vertical section of the' combined wheel and drive mechanism. -Figt- 3, isacentrallhorizontal section ofthe same. Fig. 4, is a horizontal section taken on the line -IV-IV of Fig. 2, but showing the wheel turned.

Referring to the drawings in .detai-l, 1 indicates an axle housing, in this instance the housing. for the front axle of a car, .and secured upon the endofsaid housing isa substantially hemispherical cup 2. 3 isa vertimental series of gear-teeth 8l which teeth.

are preferably formed on the inner side of a wall produced by recessinglthe upper end of said head for the accommodationof a segment gear 9 rigidlyY secured on the pivot pin and inter-geared with gearteeth 8, the said recess constituting.r an enlargementfor and at the upper end of slot?. sov that the? head of the spindle, shall be, capable `of PATENT FFICE wij; w pf, ,1, BUssnLLLEE ivris Sphere fitsv snugly-.around ythe :enferma site point with angopening '27 nal .groove 28,-,containinga1v in engagement Vwith the iv.outer A,sigde tagining apacking ringl. 4Als Vably/ contains agseriespf coiled for, holding; .the :makina eine".

This turns the pivot pin and segmental gear 9, and the latter through its intergeared relation with the head of thespindle, swings the latter in a horizontal plane, that is to say rocks said spindle around an imaginary vertical axis lying inthe vertical plane of the gear wheel 17 secured to wheel 10, this axis being diametric with respect to said gear Wheel lwhich as wheel 10 is turned, rocks in effect, around said axis without disturbing its proper intergeared relationfwith the two gear wheels 16 which ect as checks upon each other to maintain the four gear wheels in proper operative relation to each other, the lower gear Wheel 16 operating as the check when the wheelis turned to guide the car to the right,

and the upper wheel 16 as the check when I v:su

wheel 10 is turned to guide the car to the left. Itl will be apparent that the use of the packing strips and cap v14, guard against the leakage of oil from the various bearings and moving parts and the access of dust to said parts. It will also be apparent that through the mechanism described, the wheels will readily turn in response to the application of ypower on the pivots for the wheels. It

lwill also be apparent that the invention is susceptible of modification in various particulars without departing from the prinoiple of construction involved or sacrificing any of the advantages. of the appended claims.

A I claim:

1. 'In ra" combined wheel drive and guide mechanism, a driven axle, a housing therefor, a cup-, upon the housing into which the axle projects, a vertical pivot pin journaled in the cup beyond the end of the axle, a spindle projecting into the cup and provided with a curved slot and a horizontal series' of gear teeth, a segmental gear rigid on the said pin and engaging said teeth of the spindle, a road wheel journaled on the spindle, a gear wheel on the axle, a gear wheel on the road wheel, a pair oi? gearl wheels suitably journaled within the cup above and below the inner end of the spindle and intermeshing with both of the lirstnamed gear wheels, and means to turn said pivot pin to cause the segmental gear to impart rocking movement to the spindle and thereby turn the road wheel without intertering with the operation of the train of gearing between the axle and the road wheel.

2.
